Design of ionic solvents for production of man-made cellulose and silk fibers

Abstract

tensile strength (until 0,55GPa) and elastic modulus (until 25GPa) with respect to the viscose fiber (until 0,40и 10GPa, respectively). However, using NMMO as a direct solvent is dangerous. In fact, already at a temperature slightly above 140 ̊C NMMO begins to decompose with the formation of N-methylmorpholine, morpholine and the release of oxygen. This effect leads to formation of explosive mixtures.1,2
